Cat6 plenum cable for in-wall runs

This 1000 ft Cat6 bulk cable is built for plenum-rated installations in commercial or residential buildings. It uses 23 AWG solid copper conductors with a cross-member for structural integrity. The Violet CMP jacket and FEP insulation meet flame-retardant and low-smoke requirements for air-handling spaces. Installers pulling cable through ceilings or walls will appreciate the two-foot length markings on the jacket.

Tested to 550 MHz with 1 Gbps headroom

The cable is verified at 550 MHz and supports 1 Gbps transmission, providing margin above the base Category 6 specification. Unshielded twisted-pair construction keeps the cable flexible for routing through tight plenums. Solid conductors maintain consistent electrical performance over long pulls without the signal variance sometimes seen with stranded wire. The design targets reliable throughput for data and digital video networks.

CMP-rated jacket with sequential markings

The plenum-rated Violet CMP jacket uses flame-retardant PVC and FEP insulation to satisfy ANSI/TIA/EIA-568-C.2 Category 6 and ISO/IEC 11801 Class E requirements. Sequential two-foot markings let you track remaining length during installation without a separate measure. Unshielded construction means no grounding or drain wire is needed, simplifying termination. Buyers needing shielded cable for high-EMI environments or outdoor burial should look elsewhere.

Questions about this item

How is the 23 AWG solid copper cable pulled through plenum spaces without kinking?

Pull the 1000 ft roll slowly from the centre of the box; the cross-member keeps the four pairs aligned so the jacket resists flattening in tight conduit bends.

When will the Violet CMP jacket need replacement?

The plenum-rated PVC and FEP insulation are rated for the life of the building; replace only if physical damage exposes the copper conductors.

At what length does the 550 MHz rating drop below 1 Gbps?

The 550 MHz/1 Gbps rating is guaranteed to the full 1000 ft when terminated to TIA-568-C.2 and ISO-11801 Class E limits.
